The Card

MSI's RTX 4070 is instantly recognizable as a card from the Gaming X series, thanks to its unique cooler shroud style. On the other side you'll find a metal backplate that has a cutout for air to flow through.


MSI has integrated an RGB lighting element in the front of the card around the center fan, and the MSI logo on the top edge is illuminated, too.


Dimensions of the card are 34 x 14 cm, and it weighs 1217 g.


Installation requires three slots in your system.


Display connectivity includes three standard DisplayPort 1.4a ports and one HDMI 2.1a (same as Ampere).

NVIDIA introduced the concept of dual NVDEC and NVENC Codecs with the Ada Lovelace architecture. This means there are two independent sets of hardware-accelerators; so you can encode and decode two streams of video in parallel or one stream at double the FPS rate. The new 8th Gen NVENC now accelerates AV1 encoding, besides HEVC. You also get an "optical flow accelerator" unit that is able to calculate intermediate frames for videos, to smooth playback. The same hardware unit is used for frame generation in DLSS 3.


The card uses the new 12+4 pin ATX 12VHPWR connector, which is rated for up to 600 W of power draw. An adapter cable from 2x PCIe 8-pin is included (which is rated for up to 300 W). The card's default power limit is 215 W, up from the 200 W NVIDIA default. Of course the 3x and 4x 8-pin to 16-pin adapter cables from other Ampere cards will work with the RTX 4070, but the card won't need or use that much power.

Teardown

MSI's heatsink uses six heatpipes to keep the card cool. The main cooler also provides cooling for the memory chips and VRM circuitry.


The metal backplate protects the card against damage during installation and handling.
